Hello guys, I'd like to ask you a question.
How can you determine something about the server just from seeing the subnet?
How many IP adresses can this subnet have ?
What else can you tell about it ?
Any help appreciated,

- The /32 give 30 hosts + 1 bcast + 1 net base; basically 30 usable IP addresses in this subnet.
- It is an IPV4 address
- Using nslookup reverse dns finds: 184.108.40.206 is from Jordan(JO) in region Middle East
The subnet belongs to go.com.jo
- Public DNS does not seem to be setup for this
The hops are : TraceRoute from Network-Tools.com to 220.127.116.11 [94.249.x.93.go.com.jo]
- Here is the spam blacklist info: whois.rfc-ignorant.org has not blacklisted this IP

I thought that /32 stands for subnet mask 255.255.255.255 and thus it can only hold 1 host and have only one IP - 188.8.131.52 itself.
Are you sure there are 30 usable IP's ?

/27 gives you 32 Ip address not /32./32 only gives you 1 IP address.You can check below sheet for the IP range :
notation resulting subnet
netmask shorthand number of addresses
255.255.255.0 /24 [8-bit] 28 = 256 = 254 hosts + 1 bcast + 1 net base
255.255.255.128 /25 [7-bit] 27 = 128 = 126 hosts + 1 bcast + 1 net base
255.255.255.192 /26 [6-bit] 26 = 64 = 62 hosts + 1 bcast + 1 net base
255.255.255.224 /27 [5-bit] 25 = 32 = 30 hosts + 1 bcast + 1 net base
255.255.255.240 /28 [4-bit] 24 = 16 = 14 hosts + 1 bcast + 1 net base
255.255.255.248 /29 [3-bit] 23 = 8 = 6 hosts + 1 bcast + 1 net base
255.255.255.252 /30 [2-bit] 22 = 4 = 2 hosts + 1 bcast + 1 net base
255.255.255.254 /31 [1-bit] 21 = - invalid (no possible hosts)
255.255.255.255 /32 [0-bit] 20 = 1 a host route (odd duck case)
